The value of ΔH° for the reaction below is -6535 kJ. kJ of heat are released in the combustion of 16.0 g of C6H6 (l)? 2C6H6 (l) + 15O2 (g) → 12CO2 (g) + 6H2O (l)

the value of H° is below -6535 kj. +6H2O

Explanation:

6H2O answer solved

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
